TL;DR: In this article, a profile likelihood method is applied to find constraints on the existence of a potential break or cutoff in the photon spectrum of Puppis A. The analysis of the Fermi-LAT data has shown extended HE gamma-ray emission with a 0.2-100 GeV spectrum exhibiting no significant deviation from a power law, unlike most of the GeV emitting SNRs known to be interacting with molecular clouds.

Time Evolution of Broadband Nonthermal Emission from Supernova Remnants in Different Circumstellar Environments
Haruo Yasuda,Shiu-Hang Lee +1 more
TL;DR: In this article, the authors explore non-thermal emission from supernova remnants in various circumstellar environments up to 5000 yrs from explosion using hydrodynamical simulations coupled with efficient particle acceleration.

Self-Similar Collisionless Shocks
Boaz Katz,Uri Keshet,Eli Waxman +2 more
TL;DR: In this paper, the scaling of the magnetic field amplitude with distance from a relativistic non-magnetized collisionless shock was shown to be a self-similar solution, and constraints on the scaling properties of the solution were derived.

On the spectrum of stable secondary nuclei in cosmic rays
TL;DR: In this paper, the spectrum of secondary elements such as boron and lithium was computed taking into account shock reacceleration and compared with the recent observations of the B/C ratio and preliminary measurements of the bors and lithium flux.

Composition of Cosmic Rays Accelerated in Active Galactic Nuclei
TL;DR: In this paper, the authors studied the composition of the overall spectrum of cosmic rays (CRs) under the assumption that ultra high energy CRs above the energy 1017 eV are produced at the shock created by the expanding cocoons around active galactic nuclei (AGNs).
